I've often wondered what the point of dogs are as pets. Other than those dogs that serve some specific purpose such as guide dogs and sniffer dogs, I don't understand why anyone would want one. If you want some companionship, get a cat or, even better, a goldfish. It's just my opinion, but I've always been of the belief that dogs are a lot more trouble than they're worth. Most dog owners don't seem to realise that these are potentially fatal animals. My sister was attacked when we were younger by a 'really friendly dog, who would never bite anyone'- clearly their idea of friendly was different from most people's. If you ask me, all dogs are dangerous and should only be handled by trained dog handlers.
